abstract = {Desynchronizing stimulation techniques were developed to
specifically counteract abnormal neuronal synchronization
relevant to several neurological and psychiatric disorders.
The goal of our approach is to achieve an anti-kindling,
where the affected neural networks unlearn abnormal synaptic
connectivity and, hence, abnormal neuronal synchrony, by
means of desynchronizing stimulation, in particular,
Coordinated Reset (CR) stimulation. As known from
neuroscience, psychology and education, learning effects can
be enhanced by means of the spacing principle, i.e. by
delivering repeated stimuli spaced by pauses as opposed to
delivering a massed stimulus (in a single long stimulation
session). To illustrate that the spacing principle may boost
the anti-kindling effect of CR neuromodulation, in this
computational study we carry this approach to extremes. To
this end, we deliver spaced CR neuromodulation at
particularly weak intensities which render permanently
delivered CR neuromodulation ineffective. Intriguingly,
spaced CR neuromodulation at these particularly weak
intensities effectively induces an anti-kindling. In fact,
the spacing principle enables the neuronal population to
successively hop from one attractor to another one, finally
approaching attractors characterized by down-regulated
synaptic connectivity and synchrony. Our computational
results might open up novel opportunities to effectively
induce sustained desynchronization at particularly weak
stimulation intensities, thereby avoiding side effects,
e.g., in the case of deep brain stimulation.},
